It was estimated that in 1938, 40,000,000 men in the United States
shave regularly. About 3,000,000 of them shave electrically. The electric
razor industry had a dollar volume of $20,000,000, and 1,200,000 sales.
Of those the $15 Schick Dry Shaver accounted for 700,000 of the units sold.
Gary Flinn as compiled an excellent list of
shaver brands from the past.
